Abstract

An asynchronous electric machine, wherein a rotor rotating relative to a stator is provided with an electrically conductible coating. An air gap (8) between rotor (6) and stator (2) is substantially according to a formula in which formula Dr = outer rotor diameter (mm), Ds = inner stator diameter (mm), u = peripheral speed (m/s), .delta. = air gap (mm), A = a constant, whose magnitude ~ 0.3, preferably 0.7 - 1.5, suitably 1; description mm, B = a constant, whose magnitude < 150, preferably 50 - 100, suitably 70, C = a constant, whose magnitude < 1200, preferably 300 600, suitably 400;
description m/S/mm, The peripheral speed of rotor (6) is more than 100 m/s. The rotor (6) is provided on a shaft body (7) or a like with an electrically conductible coating, which is designed to be continuous to extend over the entire operative surface area of rotor (6).
